AUTOMOBILE-TIRE.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Apphcation filed January 10, 1913. Serial No. 741,216.

To all whom it may concern Be it known that I, WILLIAM E.'Dnr .n- HANTY,a citizen of the United States, residing in New York city, in the countyof New York and State of New York, have invented a new and usefulImprovement in Automobile-Tires, of which the following is aspecification.

This invention relates to automobile tires, and the object is to providean attachable anti-slipping tread, which is of simple, light, cheap anddurable construction and easy of application and removal, and which willeffectually prevent slipping. To this end I employ a solid metal tread,made of some light and tough metal or alloy and having anti-slippingprojections formed integrally on it. This tread is made in arc sections,and

. means are provided for assembling them around the wheel. 7 In thepreferred construction the tire is provided with lateral ribs orprojections, and the tread sections have hinged side portionsconstructed to hook over these ribs, the hinged side portions ofadjacent sections being connected so as to unite the sections andprevent their side portions swinging out of engagement with the ribs.

In the accompanying drawings illustrating the invention: Figure 1 is anelevation of an automobile wheel and tire with the tread appliedthereto, one section of the tread being omitted; Fig. 2 is a perspectivesectional view on an enlarged scale showing one of the sections; andFig. 3 is a crosssection on a different scale through the wheel, rim,tire and tread.

In these views, numeral 10 indicates the wheel, and 11 is the shoe of aneumatic tire having the inner tube 12. T is pneumatic tire may be ofany suitable or approved construction and may be mounted on the wheel inany usual manner. It is provided, how ever, with side ribs 13, which areformed integral with or secured to the shoe 11 in ang suitable manner,and are preferably rein orced by metal cores 14 constituting rods orcables extending all the way around the tire.

The tread is made in sections, of which.

there may be any suitable number. Each section comprises a tread portion15 having integral anti-slipping projections 16, the whoe being madeby'casting in one piece. The tread portion is extended down on the sidesof the tire for a distance, and to it are hinged hooked side portions 17for engagement with the ribs 13, the parts being hin ed together asshown at 18, or in any suita 1e manner. The adjoining ends of t e hingedside portions 17 are provided with In 19 having alined apertures,through whic are passed connecting bolts 20 having nuts 21 which may beretained by cotter pins 22. Preferably the sections are connectedtogether comparatively loosely.

lVhile the tread may be made of any suitable metal or alloy havin therequisite properties of strength wit out being too heavy, I find thatthe alloy known as aluminized steel serves very well. This mate-' rialis light and fully able to withstand all.

the stresses imposed -upon it when used for a tire tread, and iscomparatively cheap.

\Vhat I claim as new is:

1. In combination with a tire having projections on its sides, an armorconsisting of solid channeled sections adapted to fit the tread portionof the tire, and hooked side members hinged to said channeled treadsections and adapted to engage said tire projections.

2. In combination witha tire having projections on its sides, an armorconsisting of 'solid channeled sections ada ted to fit the WILLIAM E.DELEHANTY.
